Morgan/Reid Mpreg story

Hi, I'm new to livejournal and new to the community. First I love reading stories of Reid and Derek. I'm looking for a particular ,Mpreg, story where Derek's dating Tamara Barnes or is engaged with her and find out she's pregnant and Morgan and Reid used to have one night stands. But they find out that Tamara Was faking the pregnancy and Derek calls it off with her. Then Derek and Spencer get back together and Spencer gives birth to his baby; Tamara try's to kill Spencer or the baby or both at the end of the story,but Derek saves them.

Thanks you for anything you can give me.
